Color Picker

What's so great about Color Picker

Color Picker allows us to describe meaningful relationships between colors. Give this brown color, hsl(36, 73%, 10%), it's clear that if we desaturate 40 steps and lighten 70 steps we get hsl(36, 33%, 80%), a cream color.
Look at that in hex, #2C1D07 to #DDCFBB, or in rgb, rgb(44, 29, 7) to rgb(221, 207, 187), and the relationship between colors isn't evident in any meaningful way.

How to work with Color Picker

Pick a number from 0 to 360 and with saturation at 100 and luminosity at 50 and you'll have the purest form of that color. Reduce the saturation and you move towards gray.
Increasing the luminosity moves you towards white, decreasing it moves you towards black.
